1. Why is the specific gravity for infants lower than for older children?

Correct answer: D

Rationale: The correct answer is D because infants' kidneys are less developed compared to older children, making them less efficient at concentrating urine. This results in a lower specific gravity in infants. The other choices do not directly explain why the specific gravity is lower in infants.

2. A nurse administers naloxone (Narcan) to a post-op patient experiencing respiratory sedation. What undesirable effect would the nurse anticipate after giving this medication?

Correct answer: C

Rationale:

3. Which stage of motor learning is illustrated as the toddler attempts to place a shape into a container multiple times using an effective reach and grasp pattern often but makes errors?

Correct answer: B

Rationale: The correct answer is Perceptual Learning. In this stage, the toddler learns from sensory input and refines their movements over time, even though errors may still occur. This process involves improving coordination and fine-tuning motor skills based on feedback from repeated attempts.

4. During a home care visit for an infant diagnosed with gastroesophageal reflux, which parental action observed requires intervention by the nurse?

Correct answer: C

Rationale: Placing an infant diagnosed with gastroesophageal reflux in a car seat after feeding can increase the risk of reflux and aspiration. The semi-upright or high Fowler position is recommended to help reduce reflux symptoms during feeding. Adding rice cereal to formula can help thicken it and reduce reflux episodes. Administering ranitidine using a syringe is a common method of oral medication administration. Therefore, the action of placing the infant in a car seat after feeding is the one that requires intervention due to the increased risk it poses.

5. Which is NOT one of the functions of challenging behaviors?

Correct answer: C

Rationale: Challenging behaviors often serve functions related to avoiding, escaping, obtaining, or sensory needs. The question is asking for the function that does not typically apply to challenging behaviors. Choices A, B, C, and D align with the common functions associated with challenging behaviors. Therefore, 'E' is the correct answer as it does not represent a typical function of challenging behaviors.
